I finished up the air vent bracket today, I had to make a brace so that the bracket did not have a lot of movement fore and aft; I used a section of ΒΌ tubing and just flattened and bent the ends. After test fitting this with some section of Scat hose loosely fixed I turned my attention to the nut plates that hold the trim module to the baggage wall.
I removed the nut plates and installed flush rivets to the holes that held the nut plates in place. I then used some low profile screws to hold the module in place. The nuts interfered on the end that the DB25 connects so I cut a section of aluminum and tapped the holes for the #8 thread, now the module is securely held in place and not more interference with the nut on the rudder pedal.
Vent bracket and cover plate
Installed, still need to paint the cover plate to match interior
